Patent DE-2734494-A1 (DE)
Title: Crankshaft for V=cylinder IC engine - has hardening interrupted at half pin length to leave softer area between two adjacent connecting rods
Inventor: ABERMETH HUBERT
IPC: F16C3/06
Filed: 1977-07-30
Abstract: The crankshaft for a multi-cylinder engine in V-formation has hardened journals and pins, with the hardened area extending to the rounded parts of the adjoining crank webs. The hardened area is interrupted approx. at half the crank -pin length, and forms an annular softer area. This ensures that a permanent adjustment of the hardened crankshaft is possible, without the surface hardening being limited on the highly strained hollow throats and the transfer areas to the crank webs. The softer area normally is located between the fitment points of the large ends of two adjacent connecting rods.

Title: Hose end securing equipment - has flanges on half-shells pressure against bead of inserted portion
Inventor: WEINHOLD KARL ING GRAD
IPC: F16L33/12
Filed: 1977-10-19
Abstract: The equipment secures a hose end to a union boss, having a sleeve sliding axially on the boss and with a seal between them. A portion inserted in the sleeve, also with a seal between them, has an annular external flange, as has the sleeve, and half-shells hinging together and with internal flanges fit over the external ones and are secured by a clamping lever. The inserted portion (17) has a taper end (16), pref. with an annular bead (20), over which the hose end fits, the latter being held in place by flanges (22b, 21b) on the half-shells. On the inside of the latter are stops (27, 28) extending radially inwards and engaging behind the annular flange (19) of the inserted portion, so as to transmit axial forces directly onto the half-shells.
Patent DE-2747420-A1 (DE)
Inventor: MOSER WERNER
IPC: G04G99/00
Filed: 1977-10-21
Abstract: Electronic time-measuring device having an oscillator (9) and a frequency divider (10) whose output controls a switching device (12, 13), the frequency divider being assigned a storage element (7) which in the stored, active state prevents the resetting of the frequency divider in the event of failure of the supply voltage, and upon expiry of the time interval to be measured is discharged from the output of the frequency divider and rendered inactive. Consequently, the frequency divider is reset in the case of normal reconnection of the device, but not in the case when the supply voltage returns after a failure of the main source. The time-measuring device can be applied chiefly as a time switch for controlling processing and manipulating systems. <IMAGE>

Title: Hardening nickel (alloy) article surface - by applying layer esp. foil contg. boride and fusing under energy radiation
Inventor: HILLER WALTHER DIPL ING DR
IPC: B23K26/18
Filed: 1977-11-04
Abstract: In the parent patent, the surface of a Ti or Ti alloy article is hardened by (a) applying a thin layer of material contg. borides and/or carbides of Ti, V, Zr and/or Nb, and (b) fusing with surface by energy irradiation. In this addn., a Ni or Ni alloy article is hardened by (a) applying a thin layer of material contg. a boride of Ni, Co, Fe and/or Cr, and (b) fusing by energy irradiation, e.g. electron- or laser irradiation. Abrasion-resistant layers are formed, which neither break nor burst. Hardened layer thickness can be controlled. Transition from hard surface layer to basic material is gradual, ensuring good adhesion and strength under lumped or sudden loading.
Patent DE-2811494-A1 (DE)
Title: Stamping long sheet metal segments for mfg. pipe elbows - where one stroke of single punch and die makes four shaped, pierced and beaded segments
Inventor: KLEIN KARL
IPC: B21C37/28
Filed: 1978-03-16
Abstract: The elbows are used for insulating applications, and each is made from four segments with sine-wave contours. A single stamping operation is used to make three sine-shaped cuts in metal strip, thus producing four segments which are simultaneously cut from the strip. Only one punch and die is pref. used, which also produces beads at both ends of the four segments during the single stamping operation; and the latter forms two holes at each end of all four segments. One strip of sheet metal can thus be converted into four segments by each stroke of the punch. Segments can be used to make pipe elbows of different dia.

Title: IC engine using water as fuel - has electrostatic generator to oppositely charge water tanks to promote decomposition when mixed in engine
Inventor: NEIDLEIN SIEGHART
IPC: F02B43/10
Filed: 1978-04-21
Abstract: The engine drives an auxiliary electrostatic generating machine. Two tanks of water are constructed of insulating material. The output of the electrostatic generator is used to charge the water in one tank positively and the water in the other tank negatively. Inside the cylinder the charges which can be of the order of 100,000 volts, neutralise each other to decompose the water into an ignitable gas. This is then ignited and burnt in the usual way to drive the engine.

Title: Seamless garment fabric shaping - uses heat and tension to fix folded fabric to reduce manual labour
Inventor: DROSSARD ROLF
IPC: A41D1/00
Filed: 1978-05-24
Abstract: The process to form a seamless garment from tubular and/or flat stretch knitgoods, wovens or non-wovens has the fabric cut into lengths and, by the action of direct heat stretched in folds vertically to the fabric direction, and fixed while under tension. The flat material is cut to give the openings for arms, necks and pockets. The stretching and fixing process is repeated to give the fabric the garment shape. The process reduces the amt. of manual labour in the preparation of the material, and can be used for all types and qualities of fabric.

IPC: C07D471/08
Filed: 1978-06-14
Abstract: Liq. phase prepn. of C-alkyl-triethylenediamines (I) is described. A piperazine feedstock (II) is heated to 220-300 degrees in the presence of a pentavalent acidic P cpd.

Use of the catalyst (III) affords (I) in good yield with high selectivity. In addn., the liq. phase reaction avoids the formation of polymeric residues and allows ready sepn. of (I) (useful as urethane catalyst). In an example, methyl triethylenediamine was prepd. as an overhead product in 77 mol.% yield by heating a mixt. of N-(2-hydroxyethyl)methylpiperazines PhP(O)(OH)2, and 'Dowthermal A' (RTM) for 20 hr. at 245-257 degrees.

Title: Control panel for colour printer - has keys for incremental adjustment and grouped controls for exposures not integrating to gray
Inventor: HARVEY RONALD B
IPC: G03B27/80
Filed: 1979-03-23
Abstract: A control panel for a colour printer has an array of keys which are pressed to generate a variety of exposure conditions. Each key provides an incremental change in colour density or gray scale so that the operator can select the best exposure conditions for each negative. Each key provides several changes so that a matrix array of tabs provides a rapid selection of the exposure conditions. The selected conditions are displayed on a read-out so that subsequent correction can be made to the exposure. An exposure monitoring circuit provides the correct light value, with the manual modifications added by the control panel. The greater can switch in sets of correcting filters known to form basic packs for exposures not integrating to gray, e.g. artificial light exposures, predominating sand or snow areas.

Title: Carburettor for IC engine - has fuel evaporated by air suction from fine filter bed to give small droplets
Inventor: SOCHOR TONI
IPC: F02M17/22
Filed: 1979-05-05
Abstract: The carburetter has a bell shaped casing closed at the bottom and open at the top to the suction manifold. Fuel enters through the side of the bell near its bottom and saturates a filter in the base of the bell. Particles are lifted from this by the suction of air which enters the bell at a higher level through an annular air filter round the bell. There is a ring of circular openings from this filter into the bell. Evaporation of the fuel is controlled by two membranes between the fuel and air filters. The membranes are controlled by the accelerator.
